quick question

just a quick question.. im geting my two kittens in jan but they wont have had there second injuction yet. do i allow them to mingle with my other cats, who have had injections but they havnt had their annul one yet as its due 3 weeks after the kittens arrive???

Not knowing what vaccination protocol you're following, you might best direct this question to the vet that gave the vaccinations. The greatest danger of disease transmission is from the new kittens to the resident cats. If you follow the same protocol as we typically do here in the states, then I think you should be all right. But I can't give you a definitive answer.
